Update product set

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations declare a non-destructive write (readOnlyHint=false, destructiveHint=false, openWorldHint=true), but the description adds nothing beyond that: it does not say what fields can be modified, whether omitted fields are preserved or cleared, or what permissions are required. For a mutation tool, this leaves significant behavioral gaps.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

It is a single short sentence with no waste, but this brevity reflects under-specification rather than conciseness. There is no front-loaded scope or routing information to earn its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a nested-object mutation with no output schema and incomplete parameter documentation, the definition is insufficient. An agent cannot determine the updateable field set, side effects, or return behavior from the description alone.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 50% schema coverage, the description must compensate but does not. The one schema-described parameter (data, listing name/filter) is documented only in the schema, and product_set_id has no description anywhere; the tool description clarifies neither the required identifier nor the update payload shape.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description "Update a product set" merely restates the tool title and name; it is a tautology that adds no scope, verb nuance, or resource detail beyond the identifier. An agent gains nothing about what a product set is or what updating entails compared with siblings like reddit_ads_create_product_set or reddit_ads_delete_product_set.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no guidance on when to use this versus the sibling create/delete/get/list product set tools, nor any prerequisites (catalog context, required IDs). Usage can only be inferred from the name itself.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
